[Greenbuilding] Quartz Infrared Heaters

[Bob Waldrop]

I am not an expert on electrical heating devices, but the laws of 
thermodynamics dictate that it is physically impossible to get more than 1 
kwh of heat out of 1 kwh of electrical energy.  in fact, the amount of heat 
will always be less than the amount of energy expended, whether we are 
talking electricity, natural gas, wood, propane, whatever.  You can't make a 
profit, you can't break even, you can't get out of the game.

Bob Waldrop, firmly devoted to obeying the laws of thermodynamics, all the 
time, everywhere,

And if that "someone" would maybe possibly be willing to explain to the rest 
of us MATH-FREE? ;-)
